Question

我希望在我的代码中发生异常时支持回滚。

我在Spring配置文件中使用junit + datasource进行测试，使用Glassfish 2.1作为实际代码（使用jndi数据源）。

这是代码示例。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:test-web-spring-config.xml" })
public class PersistTest {

    @Autowired
    Transformer transformer;

    @Before
    public void setUp() throws Exception {

    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    @Transactional("transactionManagerTest")
    //@Rollback(false)
    // @Ignore
    public void test() {

        transformer.export();

    }

}

@Component
public class Transformer {

    @Autowired
    ContextPersist context;

    @Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
    public void export(){
        //code here
        // persist here
        context.persist();
        // to test a rollback
        throw new RuntimeException("testing rollback2");

    }

}

@Component
public class ContextPersist {

    @Autowired
    @Qualifier(value = "dataSource")
    DataSource dataSource;

    // bulk insert
    JdbcTemplate jdbcTemplate;

    @Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
    public void persist() {
        jdbcTemplate = new JdbcTemplate(dataSource);

        //.. here I insert data with jdbcTemplate.batchUpdate(....)

        // to test a rollback
        throw new RuntimeException("testing rollback1");
    }
}

该代码不会回滚。

如果我在Junit中使用@Rollback（true），则事务将回滚。但我在JUnit之外需要相同的行为。

编辑:(添加了弹簧配置）

我的项目包含一个webapp（demo.war）和一个用于DAO + businessrules的jar

在我的webapp中，我有变压器。

我在这个webapp中有一个父Spring配置，并且有一个共享的spring配置与其他webapps共享。

这里是文件。

Answer 1

您的交易经理

org.springframework.orm.hibernate3.HibernateTransactionManager

但您使用JdbcTemplate

AOP配置为在休眠操作上自动开始/提交/回滚。 jdbcTemplate不会参与任何交易。没有事务=没有回滚。它就像connection.setAutoCommit（true）;

Spring @Transaction没有在RuntimeException上回滚
